AUTOMATIC REVOLVING CAR-DUMP.

Specification of Letters Patent.

Patented Dec. 1905- Application filed April 18,1904. Serial No. 203,755.

To (all whom it may concern;

Be it 'known that I, ARTHUR Moons, a citi- Zen of the United States,residing at War Eagle, in the county of Mingo and State of WestVirginia, have invented a certain new and useful Improvement inAutomatic Revolving Oar-Dumps, of which the following is aspecification.

My invention relates to revolving cardumps, and has for its object toprovide means primarily intended for use at a mine or in connection withmining operations for dumping an entire load of coal, ore, or anysimilar material by turning the car completely over, thereby allowingthe contained material to fall out.

Mining-cars and appliances of the construction in common use arecommonly emptied by opening a gate at one end of the car and by tiltingthe car allowing the contents to slide out. The repeated sliding ofcontents soon wears the bottom of the car to such an extent that repairsbecome necessary, entailing considerable expense.

In the devices now in use wherein a car is turned over to dump thecontents thereof such rotation is accomplished by the application ofpower, which entails considerable expense. In my improved dumping devicethe rotation is accomplished by the weight of the loaded car alone, itbeing necessary to apply no power whatever.

WVith these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the accompanying drawings, Figure 1 is a side elevation of mycomplete invention mounted and showing cars in position. Fig. 2 shows avertical section on line 2 2 of Fig. 3, not showing the cars. Fig. 3 isan end View of the dump. Fig. 4 is a plan view of the clumping-platform.Fig. 5 is a side elevation of the I-beam forming such platform and uponwhich is mounted the track and car-retaining mechanism, and Fig. 6 showsthe shaft upon which such rotating platform revolves. Fig. 7 is adetailview of the brakeoperating lever. Fig. 8 is a side elevation,

and Fig. 9 is a plan view of the pawl and spring which looks therotating member. Fig. 10 is a detail view of the end of the brake-band,showing the connection of such brake-band with the brake-operating leverand the locking-pawl. Fig. 11 is a side elevation, and Fig. 12 is a planview in detail of the horn for stopping a car at the desired point uponthe rotating platform. Fig. 13 is a plan view, and Fig. 14 is a sideelevation showing the car-stopping horn and the mechanism for operatingthe same.

In the accompanying drawings like reference-numerals designatecorresponding parts throughout the several views.

In the preferred embodiment of my invention I mount my improved dumpingdevice in convenientjournal-bearings 1 1, mounted upon stationaryabutments 2 2. These abutments 2 2 also support the ends of thestationary railway 3 3 at either side of the space in which it isdesired to dump the contents of the car.

In bearings 1 1 I rotatably mount a shaft of suitable dimensions 4, andthereupon I mount I-beams 5 5 by embracing shaft 4 within the opening 6,securing it in position by keys within heyways 7 and 8, the formerlocated in shaft 4 and the latter formed in bearing-plates 9 9. WViththese I-beams 5 5 as sides I form a rigid platform by connecting theends with cross-pieces 10 10 and braces 11 11. Upon the platform soconstructed I secure ordinary railroad-rails 12 and 12, parallel withbut unequally distant from shaft 4. The rails 12 I mount nearer to shaft4 than rails 12, thus forming a track, so that when a car stands thereonthe center of gravity of the car is not over shaft 4, but to one sidethereof, so that the frame and the car thereon are in unstableequilibrium.

Upon I-beams 5 at points intermediate between the center and the ends Ierect standards 13 13, with an inwardly-turned rightangular projection14 14 at the end, and secure thereto angle-iron-retaining guides 15 15,with their openings disposed inward and downward, with the ends 16 ofthe horizontal leg of guides 15 disposed upwardly and allso dimensionedas to give clearance above and to the sides of the rails 12 and 12 toallow cars with projections 17 17 to pass closely between and beneathsuch retaining-guides to retain the cars in position when inverted.

About the middle point of shaft 4, with such shaft as an axis, Iconstruct the circular member 18, preferably having a fiat surfaceparand to standards 13 13 near the retainingguide 15 15, then by curvingsuch braces inwardly toward such circular member and bolting orotherwise securing them thereto at points 21 21.

To a framework 22, parallel with shaft 4 opposite its middle point andadjacent to circular member 18, I secure a band 23 to serve as a brake.This band passes under the device and is retained between the flanges 1919 of circular member 18. In the free end of brake-band 23 is formed aloop 24, through V which passes bolt 25.

Upon a framework similar to and opposite from framework 22 I mount twouprights 27,

rigidly secured to such framework, and between and at the upper ends 28of such uprights I pivotally secure lever 29, and upon anangularly-projebting integral portion 30 thereof I pivotallysecure links31 31, pivotally embracing at their other ends bolt 25, passed throughthe loop 24 of brakeband 23. The lever is provided near its lower endwith plunger-pawl 32, longitudinally slidable in guides 33 33 and heldnormally at its upper extremity by spring 34, which is adapted to bedepressed by pressure on connecting-rod 35, exerted by hand-lever 36.

Between the uprights 27, below and adjacent to the lower end of lever29, I mount plunger 37, longitudinally slidable in guides 38 38, hingedat 39 to pawl 40 and held normally in contact with circular member 18 byspring 41. Pawl 40 is adapted to engage one of openings 42, formed atdiametrically opposite points in circular member 18, to lock the entirerevolving portion of my device in the position shown in Fig. 3.

Upon the upper side of plunger 37 I form integrally therewith a shoulder43, adapted to engage pawl 32 when depressed to impart longitudinalmovement to such plunger through the operation of lever 29. Bearing uponpawl 40 and transverse thereto I mount bolt 44, engaged near its ends bysprings 45 45, which in turn engage at their outer ends bolt 25,embraced within the loop end of brake-band 23.

To stop and hold a car at the desired point longitudinally upon thedumping device, I place horns 46 46 beside the rail and so curved thattheir ends extend directly above the rail and are adapted to engage thetread of the car-wheels. To permit the car being pushed off the dumpingmember to allow another to take its place, I mount horns 46 upon arightangularly-shaped frame 47, as shown in detail in Figs. 11 and 12,but in pairs, the other member of the pair being the reverse of the onehere shown. This frame 47 I pivotally secure at point 48 in a horizontalposition beneath the rail and so disposed that the point 49 is betweenthe rails. To such point 49 I pivotally secure connecting-rod 50,pivotally engaging head 51 of plunger-rod 52. This plunger-rod ismounted midway between and parallel with the rails and is held by spring53, so that normally horn 46 is above the rail and in position to hold acar, but is adapted to be swung so that it assumes the position 46, inwhich position it is out of engagement with and line of car-wheel. Theend 54 of plungerrod 53 extends adjacent to supports 2 2 and ispreferably constructed cu p-shaped, as shown, to receive a thrust fromthrust-bar 55, slidably mounted midway between and parallel with therails 3 3 of the permanent track and pivotally engaging at its other endconnectingrod 56, which rod is in turn pivotally secured to lever 57,fulcrumed at 59 and standing normally substantially vertical and held inits position by weight 60.

In operating my. improved car-dumping device the rotating member thereofis placed in the position shown in Figs. 1, 2, and 3. A car loaded withthe material to be dumped is pushed along permanent track 3 3 and uponrails 12 and 12 until the tread of the wheels come in contact .withhorns 46, projection 17 being under and retained by guide 15. Lever 36is now pressed, forcing pawl 32 downward, engaging shoulder 43. Lever 29is now forced toward the car, which withdraws pawl 40 from opening 42and at the same time forces downward on links 31 31 against the tensionof springs 45 45, thus removing the tension from brake-band 23 andleaving the entire rotating member, journaled upon shaft 4 in journals1, free to rotate. It will be noted that the center of the car is notexactly over the shaft 4, so that when the revolving member is left freeto ,rotate the unequal weight on either side of shaft causes a rotationin the direction indicated by the arrow until .the car has been turnedbottom upward and, obviously, the contents dumped. The velocity ofrotation is controlled by the brake-band 23, acted on by brake-lever 29.When a complete semirevolution has been accomplished, pawl 40 is forcedinto engagement with opening 42 by spring 41 and by means ofconnecting-springs 45 draws brake-band 23 tight upon circular member 18,thereby automatically bringing the rotary movement to an end and lockingthe rotary member in position to receive another car. In case theinertia of the rotary member carries it slightly beyond the desiredpoint pawl 40, being pivoted at 39, will be lifted somewhat out ofposition. To remedy this, brake-lever 29 is pushed forward withoutengaging shoulder 43. This removes the tension from brake-band 23 andincreases the tension on springs 45, Which, bearing upon pawl 40,retracts the rotary member to the required position, and the release oflever 29 looks it. After one car has been dumped the device is inposition for dumping another car, which operation is. accomplished inlike man-- ner. This time, however, the loaded car in rotating therevolving member lifts the empty car into position to be removed, therevolution being always in one direction. To move the empty car, aloaded car to be dumped is pushed along permanent track 3 3 and theaxle, or some other predetermined portion comes in contact with lever57, forcing it forward to assume position 57, which, acting throughconnecting-rod 56, thrusts bar 55 against the end 54 of plunger 52,causing a longitudinal displacement thereof, which displacement is inturn communicated, through connecting-rod 50, swinging horns 46,outwardly until it assumes the position 46. The on-coming car can thenkick the empty car off the dump, and as the born 16 is retracted byspring 53 this horn is in position to stop the on-coming car in theproper position, when the dumping operation may be repeated.

Having thus described my invention, what I claim as novel, and desire tosecure by Letters Patent, is
